Abstract
The features of a combustion with elementary fluorine for the case of compact SiC ceramics and model substances for boron containing ceramic s (H3BO3 and Na2B4O7) were investigated with the aim of their decompos ition and analysis. On-line detection of the gaseous decomposition pro ducts by quadrupole mass spectrometry using electron impact ionisation was studied. Limitations by blanks and transport interferences were i nvestigated. Standard addition as well as the isotope dilution techniq ue were used for calibration in the case of B, C and W at the trace an d major component level.
